ABSTRACT Although once abundant, gray foxes ( Urocyon cinereoargenteus ) are purported to be experiencing a population decline in the central Great Plains, calling for the need for spatially explicit maps for targeted sampling and conservation action. Using public and state data sources, we developed a habitat suitability model across six central US states to examine distributions of relative habitat suitability and land cover associations for the gray fox. Suitable habitat was discontinuous, with numerous small patches predicted across our study area. Gray fox relative habitat suitability increased with Simpson's diversity of land cover composition and decreased with row crop cover. Our model forecasted an apparent range restriction of the gray fox in comparison to historical maps, with suitable habitat only representing 2% of its historical distribution. Our findings add to the growing body of evidence regarding the purported regional declines of gray foxes.
